Executive summary (60–90 seconds)
- If your menu is mostly “still” cold beverages (iced tea, water, cordials, clarified juices), a chilled cold drink dispenser is the low‑maintenance, lower‑power option. Common 12‑litre bowls chill quickly, spray or paddle to keep product uniform, and disassemble fast for cleaning.
- If you want lines out the door with frozen lemon, cola, coffee‑granita or cocktail bases, a granita/slushie machine delivers higher visual pull and higher GP per cup. It freezes the mix, so power draw is higher than simple chilling—but night/standby modes and insulated bowls keep costs reasonable when you use them right.
- Hygiene is non‑negotiable: clean food‑contact parts at the frequency in the manual; keep training/records; and use potable water for cleaning and for any water added to syrup mixes.
- Right‑size capacity: 1 × 12 L bowl yields ~24 serves at 500 ml; 2 × 12 L bowls yield ~48 serves. Granita prep/freezing typically needs ~40–60 minutes from liquid to ready‑serve; plan change‑overs accordingly.
- Why now: BoM’s Oct–Dec outlook signals warmer‑than‑average days and (especially) nights across most of Australia—more iced/frozen drink demand across cafés and QSRs.

Chilled vs Granita: where each wins (menu fit, speed, hygiene)
Chilled cold drink dispensers (non‑freezing)
- Best for: Iced water, iced tea, cordial, clarified juices, pre‑mixed non‑fibrous beverages.
- Strengths: Lower input power than freezing; fewer wear parts; easy daily strip‑clean; spray/paddle keeps product uniform.
- Speed to serve: Instant pour; minimal queue time; quick refill turnover.
- Food safety: Keep products ≤ 5 °C; if potentially hazardous (e.g., dairy mixes or fresh‑cut fruit), follow time/temperature controls and records.
Granita (slushie) machines (freezing)
- Best for: Frozen lemon, cola, coffee granita, mocktails/cocktails, frappé bases; some models can do dairy or alcohol (check manual).
- Strengths: High visual pull & upsell; insulated bowls; Night/Standby modes to hold product without over‑freezing; portion consistency.
- Speed to serve: Tap‑and‑go once product is at texture; initial freeze from liquid typically ≈ 40–60 min (pre‑batch in advance).
- Food safety: Clean daily; maintain correct sugar content (Brix) to avoid freeze‑ups and undue stress on seals/compressor.
| Decision | Choose this when | Examples & pathways |
|---|---|---|
| Chilled dispenser | You sell all‑day iced tea/juice/water; staff time is tight; you want lowest cleaning burden and lower input power. | Cold drink dispensers (category) |
| Granita machine | You want a frozen signature line; you can follow daily cleaning; you’ll use Night/Standby to curb power when closed. | Granita & slush machines (category) • Example dual 12 L model: Benchstar FABIGANI‑2S (2 × 12 L) |
Power draw & running‑costs: simple, honest math
Manufacturers publish rated input power (watts). Actual energy (kWh per day) depends on duty cycle: ambient temp, ventilation, product starting temp, mode (Freeze vs Night/Standby). Use the math below as an illustrative upper‑bound and a practical estimate—then validate on‑site with an energy meter.
Rated inputs you’ll commonly see
| Equipment | Typical bowl | Example rated input | Notes |
|---|---|---|---|
| Chilled cold drink dispenser | 1 × 12 L | ≈ 500 W (single bowl); ≈ 570–610 W (2–3 bowls) | Representative specs from popular 12 L models; check the exact label on your unit. |
| Granita machine (freezing) | 2 × 12 L | ≈ 650 W (dual bowl) • ≈ 1,100 W (triple) | Dual/triple models vary with brand, bowl insulation, and controls. |
Tip: Insulated bowls + Night/Standby can materially cut overnight energy for granita; chilled dispensers don’t need defrost cycles.
From W → kWh/day → $/day
Upper‑bound if a unit ran at rated power nonstop: kWh/day = (W ÷ 1000) × 24
Practical estimate with 50% duty cycle: kWh/day ≈ (W ÷ 1000) × 24 × 0.5
Cost at $0.30/kWh: $/day = kWh/day × 0.30
| Scenario | kWh/day (50% duty) | $/day @ $0.30/kWh |
|---|---|---|
| Chilled 1 × 12 L (≈500 W) | ≈ 6.0 | ≈ $1.80 |
| Granita 2 × 12 L (≈650 W) | ≈ 7.8 | ≈ $2.34 |
| Granita 3 × 12 L (≈1100 W) | ≈ 13.2 | ≈ $3.96 |
These are estimates to help shortlist. For precise numbers, measure on your site with your menu and ambient. Switch granita to Night/Standby after service to lower overnight draw.
- Use Night/Standby on granita after close; many models keep product liquid and re‑freeze faster at open.
- Pre‑chill syrups/mixes; start from ≤ 5 °C rather than room temperature.
- Give machines breathing room (vents clear) and keep condenser filters clean.
- Right‑size bowls: a single 12 L bowl that stays moving beats two bowls half‑used.
Brix, pH & seal care: avoid leaks and call‑outs
Brix matters because sugar lowers the freezing point. Too little sugar (low Brix) risks the mix freezing solid, stressing augers, seals and the compressor; too much sugar and it won’t freeze to a slush. Most commercial frozen beverage makers specify a minimum 13° Brix, with many recommending 13–18° Brix for granita texture.
Quick guide to product chemistry
| Parameter | Granita (frozen) | Chilled (non‑frozen) | Why it matters |
|---|---|---|---|
| Sugar (Brix) | ≥ 13 (often 13–18) | Flexible; follow recipe/label | Prevents freeze‑up (granita) and protects drive train & seals. |
| Acidity (pH) | Typical 2.5–4.0 for citrus/cola bases | Similar | Use pH‑neutral detergents; avoid harsh chlorine on plastics/rubber; lubricate seals as specified. |
| Pulp/fibre | Keep to a minimum; strain | Fine in some paddled units | Fibres clog taps and abrade seals; follow manual limits. |
Seal care that extends life
- Daily: inspect for weeping around bowl or tap gaskets; if re‑assembly doesn’t stop it, replace worn seals and re‑lube with food‑grade lubricant supplied/approved by the brand.
- Detergents: use pH‑neutral cleaners safe for plastics/rubber; avoid strong chlorine/bleach on clear bowls and elastomers.
- Granita only: if a tank froze solid overnight, melt fully in chill/defrost before re‑freezing to protect the compressor.
Pro tip: keep a refractometer behind the bar. It turns “I think it’s right” into a number in seconds. Log your Brix in the cleaning/records sheet alongside temperatures.
Cleaning SOPs you can hand to the team
Below are brand‑neutral SOPs aligned to common manuals for both chilled and granita machines. Always check your model’s book first, but these steps will pass most inspections and keep machines healthy.
Daily (end of service)
- Power off & drain product. Capture remaining product for disposal or same‑day use as permitted by your food‑safety plan.
- Disassemble food‑contact parts. Lids, bowls, impellers/augers, taps, drip trays. Follow the manual’s order to avoid damage.
- Wash in warm potable water (≈45–60 °C) with a non‑abrasive, plastic‑safe detergent. Use dedicated soft brushes for taps and seals.
- Rinse thoroughly with potable water. Drain completely.
- Sanitise with a food‑grade sanitiser compatible with plastics/rubber. Observe contact time, then drain/dry as the product label directs.
- Air‑dry on a clean rack. Do not put clear bowls/augers in dishwashers unless your manual explicitly allows it.
- Lubricate seals with the manufacturer‑approved food‑grade lubricant during reassembly (granita).
- Reassemble and run a short sanitiser cycle in the morning (chilled units with spray).
Weekly (deep clean) & seasonal shutdown
- Weekly: add condenser filter/vane clean; inspect gaskets for nicks or flattening; replace if in doubt.
- Monthly: vacuum condenser fins; check fan noise; verify bowl locks/taps.
- Seasonal shutdown: fully disassemble, wash, dry, and store bowls/taps in a dust‑free tub; cover machine; unplug; note restart checklist on the machine.
Records: note cleaning, Brix checks (granita), and any parts replaced. Keep at least 3 months of records with training evidence per Standard 3.2.2A.
How much to buy: bowls, litres and serves (worked examples)
Right‑sizing saves money and headaches. Start from serves per hour at peak, your cup size, and whether you need multiple flavours.
Back‑of‑napkin conversions
| Item | Rule of thumb |
|---|---|
| 12 L bowl → 500 ml cups | ≈ 24 serves per full bowl |
| 12 L bowl → 360 ml cups | ≈ 33 serves per full bowl |
| Re‑freeze from liquid | ≈ 40–60 min to first serve (brand/menu dependent) |
| Granita change‑over | Top up before half‑empty to shorten recovery |
If you need two flavours at once (cola + lemon), dual bowls (2 × 12 L) cover most cafés. Triple bowls help with a seasonal special or dairy/non‑dairy separation.
Worked example: afternoon school‑run rush
You sell 60 frozen drinks (500 ml) between 3–5 pm in summer. That’s 30 serves/hour.
- Each 12 L bowl ≈ 24 serves → two bowls hold ≈ 48 serves “on tap”.
- Top up when each bowl drops to ~½ so freeze‑recovery is quicker.
- Recommendation: 2 × 12 L granita with Night/Standby. If three flavours are must‑have, step up to a triple.
Chilled vs granita: capacity and power reference (12 L bowls)
| Type | Typical config | Total litres | Rated input (guide) | What this means in practice |
|---|---|---|---|---|
| Chilled | 1 × 12 L | 12 L | ≈ 500 W | Great for iced tea/cordial; low complexity; instant pour; easy daily clean. |
| Chilled | 2–3 × 12 L | 24–36 L | ≈ 570–610 W | Multiple flavours; still simple to clean versus granita. |
| Granita (frozen) | 2 × 12 L | 24 L | ≈ 650 W | Frozen texture; Night/Standby reduces overnight draw; higher pull/GP. |
| Granita (frozen) | 3 × 12 L | 36 L | ≈ 1,100 W | Three flavours; watch ventilation and cleaning time. |
Case study: a 90‑seat café adds frozen, keeps cleaning time flat
Venue: inner‑west Sydney café, 90 seats, heavy weekend trade. Old setup: chilled dispenser (2 × 12 L) for iced tea and lemon water. Goal: add two frozen SKUs for summer without blowing cleaning time or power bills.
What we changed (plain English)
- Equipment: added a dual‑bowl granita 2 × 12 L for lemon and cola. Kept the chilled 2 × 12 L for iced tea/water. We put the granita where passers‑by could see the bowls.
- Recipes: standardised to 14–15° Brix using a refractometer. Strained citrus pulp. Logged Brix + clean in the same sheet.
- Cleaning: stuck to a 10‑minute daily strip‑clean, with seals relubed; condenser filter added to the Friday close checklist.
- Energy: trained staff to switch granita to Night/Standby after last pour; syrups cooled in the back‑of‑house fridge for faster morning freeze.
Result in first 6 weeks
- Uplift: frozen drinks quickly hit 18–22% of beverage sales on warm days; average ticket rose with add‑ons.
- Cleaning time: stayed under 12 minutes end‑of‑day (timed twice weekly), once the team learned the disassembly order.
- Complaints/repairs: none; one minor weep at a bowl seal fixed by replacing a flattened gasket and relubing.
Decision flow: which one should you buy?
- What do customers ask for? Mostly iced tea/juice → start with chilled. Mostly frozen requests or you want a signature granita → go granita.
- How many flavours now? One → single bowl; two → dual; three or more → triple.
- Who will clean it? If your team can commit to daily strip‑clean, granita is fine. If not, chilled is more forgiving.
- Where will it sit? Granita bowls sell the product visually—front‑of‑house if you can. Keep vents clear either way.
- How warm will spring–summer be? Warmer days and nights favour iced/frozen. Stock the capacity you’ll actually use.
Compliance snapshot (AU): food safety & records
| Requirement (plain English) | What you do | Where it applies |
|---|---|---|
| Use potable water wherever water touches food or food‑contact surfaces (including ice or water used for cleaning/sanitising parts). | Plumb or fill with drinking‑quality water only; use potable water for wash/rinse/sanitise; keep evidence of supply if not on mains. | All dispensers (chilled and granita). |
| Keep potentially hazardous food ≤ 5 °C; if outside temperature control, apply the 2‑hour/4‑hour rule (time is cumulative). | For dairy or fresh‑fruit mixes, log time/temps; discard as required by the rule. Most shelf‑stable syrups are not “potentially hazardous,” but dairy mixes are. | Chilled and granita menus that include dairy/fresh produce. |
| Standard 3.2.2A—Food safety supervisor, food handler training, and evidence tool (records). | Keep at least 3 months of training/cleaning/temperature/Brix records; produce them on inspection. Attach your dispenser SOP to the file. | Most Australian food service/retail businesses handling ready‑to‑eat PHF. |
Penalties for non‑compliance vary by state/territory and by severity. In practice, poor records and cleaning attract corrective actions and follow‑up inspections; ignoring them risks infringements and, in serious cases, closure notices. Keep it simple: daily tick‑sheet + weekly supervisor sign‑off.
FAQs (hot questions we hear in spring–summer)
1) “Home” slush gadgets vs commercial machines—what’s the real difference?
Consumer units are built for occasional use, small batches and no audit trail; commercial machines are designed for continuous duty, rapid recovery, easy disassembly, replaceable seals, and compliance logging. If you sell to the public, get a commercial unit and keep records.
2) How many serves can I get from a 12 L bowl—and how quickly can I recover after a rush?
At 500 ml cups, plan for ~24 serves per full bowl. Top up before half‑empty to shorten recovery; expect ~40–60 min from liquid to ready‑serve on most granita models, faster if you pre‑chill mix.
3) Can I use fresh juice with pulp in granita?
Strain it. Pulp clogs taps and wears seals. For heavy pulp or smoothies, a chilled paddled dispenser may suit better than granita.
4) Can I freeze dairy or alcohol in granita?
Some models are cleared for dairy and moderate alcohol; many are not. Check your manual. Dairy elevates cleaning frequency and record‑keeping obligations.
5) How do I stop leaks around seals?
Inspect daily; replace flattened or nicked gaskets; use the brand‑approved food‑grade lubricant during reassembly; keep Brix ≥ 13 so you don’t freeze solid and stress the drivetrain.
6) What’s the simplest way to keep power down?
Night/Standby after close, pre‑chill mixes, ventilate intakes, and size bowls to demand. Don’t run “Freeze” all night.
